runtune
A runtime learning loop for coding agents. Turns Claude Code, Codex, Cursor, Antigravity and model-router runs into human-approved, measured changes to the agent harness: guard rules, skills, sub-agents and routes. It tunes the harness, not the model.

Could you build this?
Partial Logging agent execution traces and displaying them in a UI is simple, but building automated learning loops that reliably synthesize new prompt guardrails and routing rules requires deep agent eval expertise.
What it would actually take: The architecture requires high-throughput telemetry ingestion (e.g., ClickHouse or OpenTelemetry) to track token-level agent runs, combined with AST-level diff evaluations to verify output code correctness. The difficult core is an automated optimization engine that clusters failure modes and reliably synthesizes harness modifications without causing catastrophic regressions. Building this demands specialized expertise in automated prompt optimization, agent evaluation frameworks, and compiler/AST analysis.
